That is not how Bankruptcy Law works.
They are IN bankruptcy right now. Once you are in it, you have to go through with it. You just can't back out later and say "sorry, we didn't mean it".
Endo has to go through with it. An offer has been made for the assets, and that offer is binding. It is also for much less than Endo owes, which means creditors will not be paid back in full and therefore common shareholders get nothing.
In the future, I suggest you learn how bankruptcy REALLY works and not how amateurs on the internet pretend it does.
